In'this structure, however, 1 instead of 1employing 4the spring clamps I may employ sp-ring clips placedinteriorly ofithenipple to secure the d `same andthe cap in place.- Inthis struc? ture, the cap employed Iis indicated at 22 andsimilar tthe'cap-18 hereinbefore de# scribed.

As shown in Fig. 5, the "caprnember 25 is adapted Vto fit overv the endof 'the nipple after the saine has Ibeen turned back over'the flange 13and isfitted in oppositely disposed Vpositions with hooks 26 'to whichmay-be connecteda rubber Vbandor string 27 or lother similar device fromone hook tothe other and lying withinthe recess 17 between the ribs 16to maintain thecap 'member in place.

These various devices, however, for maintaining the airnipple in position are more or less incidental to the main featuresofthe invention which, as hereinbefore stated, reside in providing anursing bottle with van air inlet nipple orvalve so the bottle as thefood is Withdrawn therefrom will pass through any of the food in thebottle for producing the beneficial effects and overcoming thedisadvantages to which attention has hereinbefore been directed".
